Two times on three exist one cutaneous innervation hiatus from C4 to Th2. Sometimes C5 and Th1 have cutaneous territory, never C6, C7 and C8 reach the skin. It seems that for compensated absence or little extent of cutaneous territories of C5 and Th1, neighbouring posterior branches C4 and Th2 are particularly important.
